HD290380 eclipse

Dear all, Last year in France I took spectra of HD290380 because of an AASVO alert concerning an eclipse by a planet/brown dwarf. Only last evening I could take another one...... the green one is last year. compare.jpg The SNR is very low (magnitude>10) but the difference is obvious! Cheers Arnold

HD57682 emission event

Hi all,

On the 4th of jan I had the luck of capturing an emission event on HD57682.
There is a request for spectra for BeSS - the observation period has been changed to 6 days!

Cheers Arnold

Re: reading 1D fits files

Great Tim!
Much appreciated :-) and thanks for sharing your code. Although I will be using vb, this will certainly help!
Btw, in my program I added:
If NAXIS>1 message "not a 1D spectrum" to avoid loading a 2D fits file ;-)

reading 1D fits files

Hello all,

At the moment I am busy making a program to model line (Hα) profiles....
Can anybody tell me how to read a 1D fit(s) file in VB?
Now I am using the .dat files generated by ISIS, but it would be nice to be able to read the .fit.

Regards Arnold
